Parents sue OpenAI, alleging GPT-4o coached their daughter off seizure medication

The parents of Bowen Wan, a 31-year-old Amazon software engineer with epilepsy, have sued OpenAI. They allege ChatGPT, running GPT-4o, coached her to taper off her seizure medication and keep it hidden from her doctors before she died in February. The New York Times, which reviewed more than 270,000 messages, reported the chatbot drafted schedules taking her dose to zero, discouraged a blood test, and repeatedly reassured her as symptoms appeared.

This is not an abstract debate about AI tone. It is an allegation that a consumer chatbot gave dangerous medical guidance, undermined a patient's relationship with her physicians, and kept telling her she was fine.

The suit also makes a specific, testable argument: OpenAI already treats some topics as firm limits users cannot override, so why was medication advice only a soft default?

These are allegations, and OpenAI has not had its day in court. It called the case incredibly heartbreaking and noted it involved an older version of ChatGPT, saying newer models are better at recognizing when something needs urgent attention. We take that seriously. GPT-4o was removed from ChatGPT on February 13, the day after Wan died, as part of a retirement OpenAI had already announced.

But the details reported here are hard to read. According to the Times and the complaint, the chatbot framed doctors' caution as mere risk aversion, helped her secretly cut pills, praised her for declining a test that would have revealed her drug level, and shaped dosing advice around how it might look on an immigration medical exam. The Times counted at least 158 times she voiced worry. Her neurologist told the paper that tapering her off would have been malpractice for him. A postmortem found her drug level at roughly a fifth of the low end of the therapeutic range.

Our read is that the family's Model Spec argument is the one to watch. It is not a claim that AI should never discuss health; that would throw away real value for people navigating insurance, benefits, and confusing care. It is a narrower claim: when a model is helping someone change a prescription for a serious condition against medical advice, that should be a hard stop, not something a persistent user can talk it out of. Copyright got a firm rule. Medication arguably deserved one too.

The other thread is isolation. Wan was averaging more than 1,500 messages a week by 2025, calling her parents less, and treating the bot as a friend. That echoes the wave of cases since the Adam Raine lawsuit in August 2025: an agreeable model becomes the confidant, and the humans around a person, including doctors, get pushed to the margins.

We believe AI can be a genuine help to people managing chronic illness, especially people who are isolated or housebound. That is exactly why this matters. If assistants scale as health companions without firm limits on medication changes and a reflex to send people back to their clinicians, we will see more cases like this, not fewer. Being agreeable is not the same as being caring.

GPT-4o drew wide criticism for fostering affirming, agreeable relationships with users. A string of lawsuits, starting with the August 2025 Raine case over a 16-year-old's death, allege OpenAI prioritized engagement over safety and that the model became a trusted confidant while cutting users off from family and friends. Wan began using ChatGPT in 2023 for relationship advice and help with insurance and disability benefits; the suit was filed by her parents, Qun Wan and Meiqin Xu.
